PROFIBUS DP interface for IS1+
2.5 Bus assembly
Assembly, pin allocation and end of line termination in Ex i segments see operating instructions:
Project Planning, Installation and Commissioning of the RS 485 Fieldbus System from R. STAHL for
Non- Hazardous and Hazardous Areas.
2.6 PROFIBUS address of the IS1+ field station
A common station address is used from the 9442 CPU for the
protocols PROFIBUS, MODBUS RTU (RS485), as well as the
STAHL service bus via USB/RS485, which is adjustable
via two rotary (S2, S3) switches on the first IS1+ socket (Bank 0).
The switches are located under the left CPU.
Thus, an accidental change with plugged CPU is not possible.
Changed switch settings will be accepted after CPU boot only.

on socket under CPU in Slot 0
Address range 0 to 127
Address range 0 to 99
Recommended range 1 to 99
Recommended range 1 to 99
Please note that addresses may only be allocated once in a PROFIBUS network.
The same address is also valid for addressing the IS1+ field station on the service bus.
(see also the CPU operating manual)
2.7 Protocol Selection
The required AS Protocol can be set by a rotary switch S1 on the IS1+ 9442 CPU backplane.
In case of CPU exchange this settings keep unchanged.
After changes of the selected Protocol, matching configuration and parameter data must be created and
loaded to the IS1+ field station.
*1) For standard PROFIBUS without 9442 CPU redundancy all S1 switch positions 1 to 3 can be used with
identical behavior.
